Terrible service and very DISSAPONTING!!!!

I am very disappointed!!!!! I experienced network problems from the first day I got the 5G Service. I get debited on the 20th of every month. Lat month (June), I requested for a cancellation a day after my debit went off on the 21st because I couldn't deal with how the network was anymore. A few days later the router was collected. Today (20 July), 30 days after the cancellation request, I got debited even when I haven't been using the service. You can not continue to **** us like this, I need my refund ASAP.
